I found problem. HUD-Camera does not work when i create OpenGL 3.3 core context. Only clear color is visible. If not create context, all is worked.
Code: const int width(1920), height(1080); const std::string version("3.3"); osg::ref_ptr< osg::GraphicsContext::Traits > traits = new osg::GraphicsContext::Traits(); traits->x = 0; traits->y = 0; traits->width = width; traits->height = height; traits->windowDecoration = true; traits->doubleBuffer = true; traits->vsync = false; traits->glContextVersion = version; traits->glContextFlags = GL_CONTEXT_FLAG_FORWARD_COMPATIBLE_BIT; traits->glContextProfileMask = GL_CONTEXT_CORE_PROFILE_BIT; osg::ref_ptr< osg::GraphicsContext > gc = osg::GraphicsContext::createGraphicsContext( traits.get() ); if( !gc.valid() ) { osg::notify( osg::FATAL ) << "Unable to create OpenGL v" << version << " context." << std::endl; return (1); } gc->realize(); gc->makeCurrent(); osgViewer::Viewer* viewer = new osgViewer::Viewer; osg::Camera* cam = viewer->getCamera(); cam->setGraphicsContext( gc.get() ); cam->setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR); cam->setProjectionMatrix(osg::Matrix::perspective(45.0, (double)width/(double)height, 0.1, 100000.0) ); cam->setViewport(new osg::Viewport(0, 0, width, height)); //HUD-Camera created as in the example osghud osg::ref_ptr<HUDCamera> hud_camera = new HUDCamera; //Inherited from osg::Camera hud_camera->setGraphicsContext(gc.get()); hud_camera->setClearColor(osg::Vec4(0.0,0.0,0.0,1.0)); //Anyway, still see the classic blue osg color hud_camera->addChild(RTTCamera::createScreenQuad(1.0f, 1.0f, 1920.0f, 1080.0f)); //Create geometry for TextureRectangle Any ideas? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=70965#70965 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
